Unknown MySQL server host 'db' (-2)

[uguracar]

Hi,
Trying to login http://peatio:8000/admin with the user id: admin@barong.io but I'm getting "Unknown MySQL server host 'db' (-2)" error.

is anyone knows why it might be failing,(in fact db is the docker image host name of the mysql server)?

thanks
Ugur

Hi @laugh26

It is very sadly, how we can help you?

Did you change files or something in workbench source code, because seems like this problem not related to current version of workbench.

I can just suggest to try update your system, docker, docker-compose to latest versions.

Also having this issue, am curious if anyone has found a resolution to this.

I also have this error. Any solution?
